MACHINE FOR HOISTING ICE.

Specification forming part of Letters Patent No. 20,322, dated May 25, 1858-; Reissued June 13, 1865, No. 1,990.

To all whom t may concern:

Be it known that I, HLLIAM G. BRownR, of Staatsburg, in the county of Dutchess and State of New York, have invented a new and useful Machine for Hoisting and Storing Ice; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which Figure l, is a side sectional elevation of my invention the plane of section passing through the center. Fig. 2, is a front elevation of ditto.

Similar letters of reference indicate corresponding parts in the two figures.

This invention consists in the employment or use of a vertically sliding receptacle or box provided with a door or Hap and connected wit-h a windlass which is arranged with a clutch and spring catch, the several parts being so combined and arranged that by the rotation of the driving shaft the receptacle er box will be elevated, the ice discharged therefrom, the box allowed to descend and again elevated, and so on, the several parts working automatically by a continuous application of the driving power.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it. y

A, represents a framing which may be constructed in any proper way', and B, B, are two uprights attached to said framing, the upper ends of the uprights being con nected by a crosspiece a. To each upright B, a vertical guide rod C, is attached, said rods being secured in arms Z), which project one from the lower and the other from the upper end of each upright.

D, is a receptacle or box, which is fitted in an inclined position between two parallel and horizontal bars E, E, said bars being fitted -on the guide rods C, and allowed to slide freely up and down them. The back end of the box D, is provided with a door or flap c, the lower end of which is hinged to the bottom of the box, as shown at (l, and the upper end of the door or flap is secured to the box by a catch, which is a simple lever e, having a shoulder f, at one end which is made to catch over a projection g, on the upper edge of the door or flap by a spring It, which bears or presses upward against the under side of the opposite end of the lever e.

To the upper bar E, a bail F, is attached, and one end of a chain or rope G, is attached to said bail, the opposite end of the chain or rope being attached to a drum H, which is placed loosely on a shaft I, said shaft having its bearings at the upper part of the uprights B, B.

J, is an ordinary slide clutch, one part z', of which is formed at one end of the drum H, the other part j, being permanently secured to the shaft I, opposite the part 'Il K, is a horizontal bar which is fitted in guides 1, attached one to each upright B. The bar K, is allowed to slide longitudinally in the guides 75, and a spring L, which is attached to one of the uprights B, bears against one end of the bar K. The opposite end of the bar K, is pivoted to one end of a bent lever or bell crank M, which is attached to the crosspiece a, by a fulcrum pin Z, and the opposite end of the lever or bell crank is pivoted to theupper end of a vertical sliding bar N, which is attached to one of the uprights B, and has a pin m, projecting from it horizontally outward. The lower edge of the bar K, has a recess a, made in it and flanches 0, at cach end of the drum H, fit within this recess see Fig. 2.

O, O, are two levers which are attached by fulerum pins p, to each inner side of the uprights B, one to each. The front ends of these levers have each a pendent rod q, attached, and the lower ends of the rods are attached to a. horizontal bar P, which is slotted to allow the chain or rope G, to pass through, said chain or rope having a knot or stop lr, on it., the use of which will be presently explained. On the back end of each lever O, a spring s, bears, said springs having a tendency to keep the front ends of the levers O, up against the bar K, which bar has notches t, made in it to receive said levers at a certain time as will be presently explained.

QJ, is a chute the upper or elevated end of which is on a level or just below the bottom of box D, when said box is elevated. This chute leads into the store house to be lled with ice.

R, is a rod which projects out from the uprights B, B, to actuate the lever e, at the proper time.

The opera-tion is as follows: The machine is placed near the store house to be filled and adjoining the pond or river from which the ice is cut. A continuous rotary motion is given the shaft I, by any proper means. A Cake of ice is placed in t-he box D, and when sa-idfbox down at tnelower end of the machine, the clutch J, will be in gear. The drum H, will consequently be rotated with shaft I, and the box D, elevated, and when at a certain height the end of lever e, will strike against the rod R, and the door c, being released thereby it. will open by its own gravity and allow the ice, which also passes out of the box owing to the inclination of the same, toV pass outV upon andA down the chute Q, into the ice house. Immediately after the opening of the door c, and the dischargey ot' the ice, Va projecting bar (ZX, on the top oitl the box D, strikes the 'pin m, and actuates the bar N, which, through the niedium of the bent lever M, slides the bar K, and consequently the drum H, on its shaft .so t-hat the part of, of the clutch will be thrown out of gear with the part j, and the box D, will t-hen instantly descend by its own gravity to be refilled, the door c, being closed by the upper end of the chute as the box descends. When the bar K, is moved to disengage the clutch J, it is held by the levers r(y), until the box has reached its lowest point, the front parts of the levers being thrown into the notches t, by the springs s. The shaft I, is kept rotating, but as the drum H, is not connected with it the box D, remains below, but as the box'is filled the weight of ice within it, causes the knot or stop r', to draw down the bar P, and consequently the levers O, will pass out of the notches t, and the spring L, will throw the vclutch in gear and ther boX will be again so as to allow time for the box to be loaded Y.

before it commences to ascend.

Having thus described my inventionV what I claim as new and desire to secure by Letters Patent, is,

The receptacle or box D, connected with the drum or windlass H, by the chain or rope G, the drum or windlass being fitted loosely on the driving shaft I, and connected with and det-ached from it at the proper time by means of the clutch J, actuated through the medium of thev sliding bars K, N, spring L, and lever catches O, 0, the whole being arranged substantially as shown, so that the several parts will operate automatically by a continuous motion of the driving shaft and for the purpose herein set forth.
